PRINTING-FRAME.

Application filed January 11, I913. Serial No. 741,397.

To all whom it may concern Be it known that I, HENRY Co'HN, a citizen of the United States, and a resident of the city of New York, borough of the Bronx, in the count of New York and State of New York, ave invented a new and Improved Printing-Frame, of which the following is a full, clear, and exact description.

My invention has for its object to provide a printing frame having upper and lower frame members, hinged at one end, there be ing a spring for raising a glass member relatively to the lower 'frame member, so that a print may be conveniently slid off the glass, the glass being normally held down,.and in the lower frame member by back members and clamps on the upper frame member. These back members are prevented from falling through the upper frame member by the hinges, connecting the back members when the upper frame is raised relatively to the lower frame member, the hinges extending laterally, and being adapted'to rest on an inner flange on the 11 per frame member.

Additional objects 0 the invention will appear in the following com lete specification, in which the preferred orm of the invention is disclosed.

In the drawings similar characters of ref erence indicate corresponding parts in all the views, in which Figure 1 is a, perspective View of the invention; Fig. 2 is an enlarged fragmentary plan view of ,the invent on, with parts broken away to show the 5 ring for raising the glass member; Fig. 318 a front elevation of the invention ;'F:ig 4; is a sectional view on thelineA Aof Fig. 2 with the printing is a similar sectional and with the upper frame member supported by the indicating means; Fig. 6 is a sectional view of the printing frame onthe line 6-6 of Fig. 2; and Fig. 7 is a fragmentary sec tional view showing the position of a holding screw as'it is 'being turned to hold' the' rear of the glass in place.

By referring to the drawings it Wlll be seen that a printing frame has a lower open. frame member 5 with inner flanges 6, ex-

tending into the opening, these flanges 6fbe ing spaced from the upper face? of the lower frame member 5. A glass member 8 is normally disposed on these flanges 6, a spring 9 being disposed on the forward flanges 6*,yhich serves to hold the forward frame member 12. 'm'embers 15 is covered with a soft material end of the glass member 8 yieldingly upward, and at or above the plane of theupper face 7 of the lower frame member 5, so that a print disposed on a negative 10 supported by the glass member 8, maybe slid. forwardly, and over the forward end of the lower frame member 5, and free from the printing frame. The rear of the glass member 8 is held downby a bent screw 8 which when in normal position has its head 8? disp osed against the rear of the glass member 8.

0 this lower frame member 6 there is hinged at th rear 11 an upper open frame member 12, this upper frame member 12 having at its sides inwardly extending flanges 13. Disposed in for closing the openings 14 in the upper frame member 12, there are two back members 15, which are hinged together 'bythe hinges '16, as best shown in Fig. 1 of thedrawings. These hinges16 extend beyond the sides of the I back members 15, and over the flanges 13, so that the downward movement-of the back members 15 relatively to the upper frame member 12 is limited. The ba'ck'members 15 are provided with the usual spring clamp members-17, which have ends 18, for enaging with the flanges 19 on the upper The bottom of the back 20, in the usual manner.

When the prlntmg frame 1S opened, as

shownin Fig. 5 of the drawings, a piece of.

printing paper may be disposed on the'negative l0, and the printing frame may then be closed, the back member 15 pressing the negative and the glass member 8 downward and against. the resiliency of the spring 9, until the glass member 8 rests on the flanges 6. The pressure against the glass member 8 then-serves to force the back members 15 upward, and against the resiliency of the spring clamps 17, so that the hinges 16 will be raised. above the upper plane of the *fl'anges 13. For holding the upper member 1 2":down on the lower frame member 5 I provide a clamp member 21, which is pivoted to a bracket 22 by a pin 23, these brackets 22 being secured to the upper frame member 12. The clamp member 21 has outwardly disposed catch members 24, for engaging the projections 25 on the lower frame member The upper portion of the clamp 21 1S held yieldingly outward from the upper frame member 12, by a coiled spring 26 which is wound on thepin 23 between the outwardly extending ends 22 of thebracketf2 2fai1 1 which has a terminal 23a pressing against the top of the clamp 21, and a secondtermie the negative 10, and the upper frame member 12 has been closed against the lower frame member 12, either one of the back members;

15 may be opened bymeans of a spring clamp 17, so that the photographer ma I termme if the printin has' been comp 'eted,

When the printing is ound to be completed the back member 16 i'which hasbeen opened is again closed, and thefforward end of the upper frame'm'ember12 is freed froni the forward end'of the lower frame member 5, by pressing inwardlythe upper or'ti on of the clamp 21, which frees the catc "'membe1f-'s 24 fromthe rojections 25,'and asthe upper frame mem er. 12 is raised the spring 9 serves to raise the forward ortion' of the 1 glass 8 so that the print onv e negative 10 may-be slipped forwardly and freed from the printing-frame.

Having thus 'described'm y' invention, I
